Is it me or is that just odd. I mean, I like to have my tanks in rooms that I spend a lot of time in. Now I wouldn't mind having a really big cylinder shaped tank in my family room, I like the idea of that, but it'd have to be for something like seahorses, not enough swimming room for most fish (or else we're talking a 3' diameter cylinder)

I think he means a circle about 3-4 ft. in diameter that you stand in the middle of to shower with the tank creating the walls of the shower. Cool idea, but the logistics of something like that would be huge (and very expensive).
